Planck Snaps Its First Images of Ancient Cosmic Light

Pasadena: The Planck mission has captured its first rough images of the sky, demonstrating the observatory is working and ready to measure light from the dawn of time. Planck - a European Space Agency mission with significant NASA participation - will survey the entire sky to learn more about the history and evolution of our universe.

The space telescope started surveying the sky regularly on Aug. 13 from its vantage point far from Earth. Planck is in orbit around the second Lagrange point of our Earth-sun system, a relatively stable spot located 1.5 million kilometers (930,000 miles) away from Earth.

"We are beginning to observe ancient light that has traveled more than 13 billion years to reach us," said Charles Lawrence, the NASA project scientist for the mission at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "It's tremendously exciting to see these very first data from Planck. They show that all systems are working well and give a preview of the all-sky images to come."
